Clang and GCC now offer sanitizers. Uri and I have been testing Crypto++
under the Undefined Behavior Sanitizer (UBsan) and Address Sanitizer (Asan)
for some time now.
Using them usually requires us to modify the makefile. The patch below adds
proper support for them so we can do things like:
make ubsan
./cryptest.exe v | grep error
Are there any comments or objections?
